When modeling rubber like material in explicit FEA, you can't set Poisson's ratio as 0.5. Why? What would happen in the solver if you do that?
I noted that it leads to an infinity in the stiffness matrix but he wanted more details.
Yes, I took the course in my undergraduate education. But most of my experience is in aerospace static stress analysis. I'm assuming you would have a good documentation there for new starters in automotive. (they literally didn't have anything to study & etc.) Less
Stiffness, which is related to the material and shape of the spring. The greater the stiffness, the higher the frequencies. Mass. The greater the mass, the lower the frequencies. Omega = sqrt(k/m). Less
